CLEAN-OUT FOR BURNER/S.

Application filed January 26,- 1920. Serial No. 354,098..

New York, have invented a new and Improved Clean-Out for Burners, of which the following is a full, clear, and exact description. I

The present invention relates to new and useful improvements in self-blowing torches, and it pertains more particularly to an improvement on the device disclosed in United States Patent No. 1,330,696, granted to me February 10, 1920, to which cross reference is here made.

In the device described in the patent above mentioned, there is a main receptacle, a starting tube, a retort tube, and a burner tube. The burner tube is substantially U- shaped in form and is provided with a burner opening through which the gas passes in the presence of the flame of the starting tube and is ignited. In actual practice it has been found that from various reasons owing to its constricted size, the burner tube becomes clogged or choked, and its peculiar construction and arrangement prevent of its being cleaned without the entire removal thereof.

It is the primary object of the present invention to so construct the plugs or caps closing the ends of the fuel and retort tubes that a passage is presented in aline nent with the passage through the constricted burner tube in order to facilitate the cleaning thereof.

With the above and other objects in view, reference is had to the accompanying drawings in which- Figure 1 is a side elevation of a torch constructed and arranged in accordance with the present invention;

Fig. 2 is a front elevation thereof, and

Fig. 3 is a detail sectional view taken on the line 3-3 of Fig. 2.

Referring more specifically to the drawings, the reference character 5 designates a fuel receptacle, and projectlng from the upper end thereof is a centrally disposed starting tube 6. This tube 6 is bent outwardly as shown in Fig. 1, and is filled by a wlck 7, said tube projecting downwardly into the receptacle 5 a sufiicient distance to permit of a thorough saturation of the wick 7 by the fuel contained in the main receptacle 5.

Projecting from the top wall of the. receptacle 5 are two tubes 8, and said tubes are curved upwardly and outwardly in such a manner that they overlie the starting tube 6, asshown in Figs. 1 and 2. The reference Patented May 24, 1921.

character 9 designates a substantially U- shaped burner tube, and said burner tube underliesthe retort tube 8 and overlies the burner portion of the starting tube 6, as shown in Fig. 1. This burner tube 9 is pro vided intermediate of its ends with opening'lO, and said burner opening 10 is positioned in sucha'manner that the gas generated in the retort tubes 8 will be projected transversely of the burner end of the starting tube 6.

By reference to Fig. 3, it will be noted that each of the retort tubes 8 has its outer end closed by means of a plug 12, which is suitably secured within its retort. This plug is provided with a passage 13, which extends therethrough in substantial alinement with the axis of its respective retort tube 8, said passage permitting of the insertion of a suitable tool used to position the wick 14 within the retort tube 8. Each passage 13 is adapted to be closed by means of a screw 15, it being understood that a portion of said passage is internally threaded to recelve said screw. Passing through the plug 12 from the top to the bottom thereof, is a passage 16. Removably secured as by threaded engagement with the interior of the passage 16 at the upper end thereof, is a screw 17, and said screw is adapted to serve as the closing medium of said passage. The lower end of the passage 16 is enlarged as at 18, and this enlarged portion 18 is adapted to receive the end 19 of the adjacent leg of the U-shaped burner tube 9.

It is to be understood that the construction shown in Fig. 3 is the same on the free end of each of the tubes 8, and that the end of each of the legs of the U-shaped burner tube 9 is bent upwardly as indicated by the reference character 20 to provide for its attachment within the enlarged portion 18 of the passage 16 of its adjacent plug 16. By this construction it will be apparent that should the burner tube 9 become choked or stopped up, upon removing the screws 17 a suitable flexible wire or other cleaning tool may be passed through the passages 16 and the passage of the burner tube 9, to remove the foreign deposits within the tube and thereby thoroughly clean the same.

a burner Claims: 1. In a self-blowing. torch, a plurality'or retort tubes, a burner tube supported by the retort tubes, said burner tube havin a passage therethrough, and plugs secure to the burner tube and closing the ends of the retort tubes, said plugs being provided with V passages in alinement with the passage through the burner tube.

- 2. In a self-blowing torch, a plurality of retort tubes, a burner tube supported by the retort tubes, a plug closing the end'of each I of said retort tubes, said plugs being'provided with a plurality of right angular passages which passed therethrough and establish communication between the retort tubes and theburner tubes, and means for closing that portion of the passagesin the outer walls of the closin plugs.

V 3. In a 'self-blowlng torch, a plurality of retort tubes, plug members supported in the ends of said retort tubes,'a burner tube havsaid passages.

ing a passage therein, said plug members being provided with a plurality of right angular passages arranged within said plug members and adapted to establish communi cation between the re'tort tubes and the 7 burner. tube, one of the passages of the.

with a plurality of angular passages which are adapted to establish communication be tween the'retort tube and the burner tube, and are adapted to permit of theinsertion of a cleaning tool to the burner tube and retort tube, and screwthreade'd elements for closing the open end of each of said pas- 1 sages, substantially as described.
